Michael, your problem might be (and I stress might be) related to a known bug . What we will have to do is run you through the standard troubleshooting guide to see if it helps any. If you can, please follow Steps 1-3 of our Solving Technical Issues wiki page, taking special care to temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, please follow Step 4 , including posting all of the necessary information, so that we can further assist you. This is to help collect information for further analyst.
